[ARC5] Non Directional Beacons

I am a member of a radio club that will retreat to a cabin deep in the woods of a state park for 2 or 3 weekends during the DX season. Computers forbidden!! Until one long time member brought his Perseus SDR and  computer, an active antenna about 6 inches long (which he threw into a pine tree next to the cabin) and started listening. To top it all off, he recorded 5 minutes of the NDB band and promised to report what he heard later. It took about 6 months. Using electronic filters as narrow as 1 Hz (yes, one Hertz) he had pulled out over 500 beacons.

Last winter, using a refurbished BC-453 connected to a low end-fed wire and despite the
noise level, I managed to record over 50 NDBs in only two nights of listening.

One, a Canadian beacon in the far north west corner of NWT, was at least 2500 miles away,
and was running only about 50 watts output.

Another was in the Carribean somewhere.

NDB DX-ing is fun.
